Peering DBの情報をAPIをつかって取得する

Last updated at Posted at 2021-07-01

Peering DBからAPI経由で情報を抜き出して、Power BIで可視化したい

Power BIでもTableauでも、可視化や分析にはデータがないとなにもできません。
ということで今回はだれでもアクセスできるPeering DBの可視化をします。
Power BIで～と書きましたが、長くなってしまったためPower BI部分は別の記事で書きます。
この記事は主にPeering DBのAPIについてです。
Pythonを使ってます

Agenda

  1. Peering DBとは
  2. 軽く触ってみる
  3. 目的別コード置き場
  4. 参考資料

１．Peering DBとは

AS番号を持つ組織のネットワーク同士が相互接続することを、PeerやPeeringと呼ばれています。具体的にはBGPというプロトコルを両組織のルータで動作させ、お互いの組織のIPアドレスやAS番号を設定することでPeeringを実現します。

２．軽く触ってみる

https://peeringdb.com/api/
Peering DBのリンクへとりあえずリクエストしてみる。
これから先のクエリを与えたりアクセス先がかわっても、このdataとmetaの二つの要素に分かれているので、
基本はここからdataだけを抜き出すことになる

コード

#! /usr/bin/env python
# -*- coding: utf-8 -*-
import requests
import json
import pandas as pd
def get_net_list():
    pdb_url = 'https://peeringdb.com/api/'
    r = requests.get(pdb_url)
    origin = r.json()
    return origin

if __name__ == '__main__' :
    exp = get_net_list()

結果

{
  "data": [
    {
      "fac": "https://peeringdb.com/api/fac",
      "ix": "https://peeringdb.com/api/ix",

    }
  ],
  "meta": {}
}

それぞれのリンクでは各リストが出力できる

facility list

https://peeringdb.com/api/fac
Peering DBに登録されているデータセンターなどのファシリティの一覧はここから一覧が取得できそう。
緯度経度もあるが、入っているところもあればないところもあるので、ここはひとつ課題。

３．目的別コード

もともとはPeering DBから指定のIXはどこに入っているのか、そもそもロケーションってどれくらいあるのだろうとかを出力したかったが、
難しく考えずに必要なリストを呼び出してKeyIDでリレーションを組めばよさそうなことに気づいた。（当たり前か）
例えばCSPでフィルタしてロケーションを紐解こうとすると、~/net/Idで毎回コールする必要があるかと思ったらそうではなくて、
~/netfacをつかってそれぞれプロバイダーとFacilityのリストをリレーション組むだけでよかった。

csvへFacilityのリストを出力する

    # Peering DBのリクエストへの結果でもあったように、meta部分は除いてデータフレームへ落とし込む
    df = pd.json_normalize(origin['data'])
    # csvへ出力
    csv_data = df.to_csv('facilityList.csv')
    return origin, df

    # get data center list
    fac_list = get_peeringdb()

あとはURLを変えて取得するだけ。
可視化自体はPower BIでやりたかったので、
これらを使ってPeering DBの可視化をやっていく。
